Re: cooling your tent or van

Just had a great time with my cooler. it was a total life safer. A few things I learned: 1. Building the cooler was not difficult! I was intimidated by it in the past as I thought I was not a handy person, but it really just involved sourcing the parts and mashing them together. It was only one even...

Buy online from Amazon and ship to Blaine. There are a few options for this. I used one called Ship2Blaine which is free/by donation and run out of someone's house -- 10 min drive from Blaine city center.

Re: Practical Camp Lighting

This kind of light is good for chilling, but doesn't quite reach the level of "bright" that is sometimes nice (e.g. while cooking dinner). If you are in an enclosed space where light will get thrown on the ceiling and walls, it will be brighter. But I suggest getting a high-brightness camp...

Re: Power Needs = Batteries & Solar Panel???

Figjam coolers use 1 to 2 Amps at 12V, depending on the power of your fan and pump, so figure out how many hours you want to run them. e.g. 3 hours/day * 2 coolers * 2 amps = 12 Amp-hours per day. Those lights won't work on a 12V battery (3AA's = 4.5V, what they're designed for), so no you cannot ea...

Re: Help refining lighting setup with 4 x 5m RGB LED strips

This seems like a reasonable plan. You'll need a 12V power supply. Look at the power ratings on the LED strips and see what the max power is -- maybe 30 W or so -- you would ordinarily then buy a 40W supply and be done. With four strips you need to add up their power requirements, so maybe you need ...

Go simple -- get something with integrated batteries that runs on standard sizes.

Re: Lighting Plan - requesting comments

Re: the math I find it way easier to convert battery capacity to Watt-hours, rather than working in Amp-hours. A 100Ah-12V battery has max 1200 Watt-hours, of which you can count on about half, so 600 Watt-hours. Which is 60 hours of your 10W bulb. Almost enough for the 80 hours you wanted; add a tr...

Re: Battery advice for lighting our art car

I run my camp's lights off of deep cycle batteries every night. One modest power inverter should work fine for all of this but the battery will be drained in a few hours, most likely. You have to do some math here to figure it out. A deep cycle marine battery is generally rated at about 100 Amp-hour...

Good high-capacity 12V rerchargeable battery pack for LEDs?

Hi, I'm planning a wearable LED project that needs 12V batteries. Current draw may be in the range of 0.1 to 1.0 Amps, based on specs I'm seeing. (More likely on the lower end, I would guess). Since I want it to last a while I want a high capacity battery pack. I'm seeing this stuff on ebay and othe...

Surely a power inverter would be the simplest, just run the lights off the vehicle engine? You already have a generator, charger, and battery under the hood... The only concern would be if the load is too high for the little golf cart motor, but if you light it with LEDs it won't be more than a few ...
